IMPROVE-MENT IN GRAIN CLEANERS AND SCOURERS.

Specification forming part of Letters Patent N0. 153,169, dated July 2l, l874 application filed December 23, 1873.

To all whom 'it may concern:

Be it known that I, WILLIAM IV. INGRA- HAM, ot Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Grain Smutters and Scourers, of which the following is a specification:

This invention relates to a novel casing and cylinder for grain sm utters and scourers, which shall be easily made, and exceedingly durable and etticient; and the invention consists in making` the outer casing or eoncaveof a coil of wire cable, secured together by some proper means, so that it shall preserve its shape. Such a concave presents a surface full of minute interstiees and projections, formed by thc wires twisted upon each other, and is, moreover, pervious to the air, which can pass freely through the coil. rlhis surface I have found to be peculiarly adapted to the scouring of grain, and exceedingly durable, improving, in fact, with wear, because the roughness of the surface is increased after the ends of the worn wires project as they are worn in twain, all of which will be more fully hereinafter specified.

In the accompanying drawing, which forms a part ot' this specification, Figure l represents a top or plan view of the machine. Fig. 2 is a front elevation of the same, with a portion of the exterior jacket removed to show the outside of the coil ot' cable forming the exterior stationary concave cylinder. Fig. is a vertical central section of Fig. 2 on the line x x, and Fig. 4 is a horizontal section of the interior cylinder.

Like letters of reference made usc of in thc several figures indicate like parts wherever used.

. ln the said drawing, A represents the extecylinder revolves wit-hin the exterior one, and the grain is fed between the two and acted upon by the opposed wire-rope surfaces. The two cylinders are surrounded eXter-iorly by a casing or jacket, O, and mounted in a framework, D. The shaft and pulley E F serve to rotate the inner cylinder.

To this apparatus may be fitted a fan and the other appliances of a sin utter and scourer. (Not shown in the drawings.)

Instead of using wire cable wound spirally in a coil, twisted iron rods may be employed; or a single iron rod, twisted as some light` nin g-rods are twisted, may be substituted, and wound spirally around, to form either or both of the cylinders. ,I deem this substitution of a twisted rod or rods an equivalent to the cable, as it may be coiled in the same form, and until it is worn down smooth would present a similar surface. I prefer to -use the wire cable, however, and recommend that as the best.

Having thus fully described the construction and operation of my invention, I claimrlhe surface for scouring grain consisting of layers of wire rope, substantially as specified.
